[0003] Existing technologies rely on manual alignment and temporary fixation, which have the following problems:

[0004] 1. Poor positioning accuracy: Under curved surfaces (tunnel arc templates) or complex working conditions, the angle and position of the channel are difficult to control accurately, resulting in a high rework rate;

[0005] 2. Low installation efficiency: The lack of anti-rotation design makes the groove prone to shifting when tightening bolts, requiring repeated adjustments;

[0006] Therefore, a channel installation device integrating rapid positioning, stable installation, and environmental adaptability is proposed. Utility Model Content

[0039] Example

[0040] The tunnel duct installation quick positioning device provided in this embodiment, such as Figures 1-3 As shown, it includes template 1, channel 2, anti-rotation component, positioning and fixing component, and bonding component, wherein:

[0041] Template 1 is an arc-shaped or straight plate-like structure, and channel 2 is provided on one side of template 1; anti-rotation component is provided on channel 2, and positioning and fixing component is connected to anti-rotation component, working together to fix channel 2 on one side of template 1 to limit the rotational displacement of channel 2; adhesive component is provided on anti-rotation component to adhere anti-rotation component to channel 2; anti-rotation component, positioning and fixing component and adhesive component are provided in at least two sets.

[0042] Template 1 adapts to curved / straight structures (covering tunnel and bridge scenarios), anti-rotation components and positioning and fixing components work together to limit the rotational displacement of channel 2, bonding components assist in pre-fixation, and multiple sets of components (≥2 sets) distribute the force, achieving the overall effect of rapid channel positioning, multi-condition adaptation, and enhanced installation stability.

[0043] Specifically, in this embodiment: the anti-rotation component includes an anti-rotation block 3 disposed inside the channel 2 and a positioning bolt 4 fixedly installed on the side of the anti-rotation block 3 facing the template 1. The channel 2 is provided with a through hole for the positioning bolt 4 to pass through, and the template 1 is provided with a hole 9 for the positioning bolt 4 to pass through. The positioning bolt 4 is disposed by passing through the through hole and the hole 9 in sequence.

[0044] The anti-rotation block 3 fits against the side of the channel 2, and the positioning bolt 4 passes through the through hole of the channel and the template hole 9 to build a preliminary constraint system for circumferential anti-rotation, providing a directional reference for subsequent fixing and solving the problem of rotational offset during channel installation.

[0045] Specifically, in this embodiment, the anti-rotation block 3 has a rectangular or trapezoidal cross-section. The anti-rotation block 3 uses a rectangular / trapezoidal cross-section, which increases the contact area by adapting to the side profile of the channel 2, strengthening the circumferential limiting stiffness, and improving anti-rotation stability and adaptability (compatible with different channel structure designs).

[0046] Specifically, in this embodiment: the positioning and fixing component includes a connecting screw 6; the connecting screw 6 passes through the hole 9 and is threaded onto the positioning bolt 4; a fastening nut 8 is threaded onto the connecting screw 6, and the fastening nut 8 is located on the side of the template 1 away from the channel 2. By tightening the fastening nut 8, the channel 2 is pressed against the template 1. The connecting screw 6 and the positioning bolt 4 are threadedly engaged, and the fastening nut 8 is axially locked. Combined with circumferential constraints, a two-way limiting mechanism of "circumferential anti-rotation + axial fastening" is formed to ensure that the channel 2 and the template 1 are firmly attached and to eliminate installation gaps.

[0047] Specifically, in this embodiment: a sealing gasket 7 is fitted on the connecting screw 6, and the sealing gasket 7 is located between the fastening nut 8 and the template 1. The sealing gasket 7 fills the gap between the fastening nut 8 and the template 1, blocking the intrusion path of water and dust, thereby achieving a sealed and reinforced connection, adapting to the humid and dusty environment of tunnels / bridges, and improving the durability of the device.

[0048] Specifically, in this embodiment: the sealing gasket 7 is a silicone rubber gasket with a Shore hardness of 50-70HA. The use of silicone rubber in the sealing gasket 7 utilizes its elastic deformation capability to compensate for installation errors and buffer tightening stress. Simultaneously, relying on the weather resistance of silicone rubber, it maintains a long-term sealing effect, ensuring both sealing reliability and structural protection.

[0049] Specifically, in this embodiment: the bonding component is an adhesive pad 5, which is attached to the side of the anti-rotation block 3 facing the template 1, and is used to adhere the anti-rotation block 3 to the channel 2 to facilitate subsequent construction. The adhesive pad 5 is pre-attached to the surface of the anti-rotation block 3, and quickly adheres to the channel 2 during construction, realizing the pre-positioning of the anti-rotation component, avoiding displacement of the anti-rotation block during construction, simplifying the installation process, and improving alignment efficiency.

[0050] Specifically, in this embodiment: the adhesive pad 5 is made of butyl rubber or epoxy resin, with a thickness of 2-5 mm. The adhesive pad 5 uses butyl rubber (high viscosity, elastic buffer) or epoxy resin (high strength adhesion), which not only ensures the stable connection between the anti-rotation block 3 and the channel 2, but also absorbs vibration and fills gaps through the material properties, thereby strengthening the overall structure and vibration resistance.

[0051] Specifically, in this embodiment: Template 1 is made of high-strength aluminum alloy or Q345B steel plate, and the surface is treated with anti-slip coating. The use of high-strength aluminum alloy / Q345B steel plate for Template 1 ensures load-bearing strength (to resist construction loads); the anti-slip surface treatment reduces component slippage, helps maintain positioning accuracy, and improves the safety of construction operations.

[0052] Specifically, in this embodiment: one end of the connecting screw 6 has a threaded groove, and the other end of the connecting screw 6 has an anti-rotation hexagonal hole 10. The threaded groove at one end of the connecting screw 6 is adapted to the positioning bolt 4, and the anti-rotation hexagonal hole 10 at the other end is used for tool clamping. This prevents the connecting screw from rotating during installation, simplifies the insertion and tightening operation, and improves installation efficiency and precision control.

[0053] In summary, the working principle of the rapid positioning device for tunnel installation provided in this embodiment is as follows:

[0054] This device, through the synergistic action of the anti-rotation component, positioning and fixing component, bonding component, and template 1, constructs an integrated mechanism of "anti-rotation → pre-fixation → tightening → sealing":

[0055] 1. Circumferential anti-rotation constraint (anti-rotation component):

[0056] The anti-rotation block 3 fits against the side of the channel 2, and the positioning bolt 4 passes through the through hole of the channel 2 and the hole 9 of the template 1 to form a circumferential limiting system to prevent the channel 2 from rotating and shifting during installation.

[0057] 2. Pre-fixation aids (adhesive components):

[0058] The adhesive pad 5 is attached to the anti-rotation block 3, and the anti-rotation block 3 and the channel 2 are pre-fixed by the adhesive, so as to avoid the displacement of the anti-rotation block 3 during construction and simplify the alignment process.

[0059] 3. Axial fastening and locking (positioning and fixing components):

[0060] The connecting screw 6 is threaded to the positioning bolt 4, and the fastening nut 8 is axially locked. Combined with the circumferential constraint, a two-way limit of "circumferential anti-rotation + axial fastening" is formed to ensure that the channel 2 and the template 1 fit tightly and eliminate the installation gap.

[0061] 4. Enhanced sealing and cushioning:

[0062] The sealing gasket 7 fills the gap between the fastening nut 8 and the template 1, preventing water and dust from entering;

[0063] The adhesive pad 5 simultaneously fills the gap between the channel 2 and the template 1, serving both buffering and sealing functions, and adapting to vibration environments.

[0064] 5. Multi-group collaboration and operation optimization:

[0065] At least two sets of anti-rotation, positioning and fixing, and bonding components are provided to distribute the force and improve stability;

[0066] The anti-rotation hexagonal hole 10 of the connecting screw 6 is used for tool clamping, preventing rotation during installation and simplifying the insertion and tightening steps.

[0067] How to use

[0068] Step 1: Preprocessing and Component Preparation

[0069] Machining template 1 includes mounting holes (corresponding to holes 9 in channel 2) and positioning screw holes (fitting positioning bolts 4);

[0070] Prepare components such as anti-rotation block 3, adhesive pad 5 (attached to the side of anti-rotation block 3 facing the channel 2), and connecting screw 6 (prefabricated threaded slot and anti-rotation hexagonal hole 10).

[0071] Step 2: Pre-install anti-rotation components

[0072] Fix the positioning bolt 4 to the anti-rotation block 3, and use the adhesive pad 5 to pre-attach the anti-rotation block 3 to the inside of the channel 2 to complete the initial positioning.

[0073] Step 3: Channel alignment and fitting

[0074] Align the channel 2 with the template 1 so that the positioning bolt 4 is inserted into the hole 9 of the template 1;

[0075] Insert the connecting screw 6 into the hole 9 on the other side of the template 1, and screw the threaded end into the adapter interface of the positioning bolt 4.

[0076] Step 4: Tightening and Adjustment

[0077] Insert the sealing gasket 7 and tighten the fastening nut 8; during the process, use a tool to clamp the anti-rotation hexagonal hole 10 of the connecting screw 6 to prevent the connecting screw 6 from rotating on its own;

[0078] Check the position and angle of channel 2 (based on the anti-rotation block 3 for limiting) and adjust it to the required accuracy; at the same time, confirm the fit and sealing of the adhesive pad 5 and the sealing gasket 7.

[0079] Step 5: Multiple expansion installations

[0080] Repeat the above steps to install at least two sets of components to distribute the stress points of channel 2 and enhance the overall installation stability.
